Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum, and in particular to a transport trolley for aluminum electrolytic production. Background Technology

[0002] In the electrolytic aluminum production process, daily measurement and adjustment of the liquid electrolyte level according to technical standards is a routine task. Currently, the method for adjusting the liquid electrolyte involves operators first scooping excess liquid electrolyte from the electrolytic cell (which exceeds the technical standard) into an electrolyte tank cart. The cart is then moved to the electrolytic cell requiring replenishment, aligned with the aluminum outlet, and the operator tilts the cart to pour the liquid electrolyte into the cell. Because the electrolyte tank cart is quite heavy, the operation requires two people working together, resulting in low efficiency. Furthermore, the large volume of liquid electrolyte poured out can easily cause splashing, posing a safety hazard to the operators. Utility Model Content

Detailed Implementation

[0023] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, this embodiment discloses a transport trolley for aluminum electrolysis production, including a balance beam 1, axles 6, and an electrolyte tank 7. A hand-held crossbar 2 is fixed to the rear end of the balance beam 1, and a fork-mounted frame 3 is fixed to the front end. The fork-mounted frame 3 is U-shaped, and each of its two side support arms has an ear groove 301. A boss 4 and a limiting pin 5 are respectively provided on the left and right sides of the top opening of the ear groove 301. The boss 4 is fixed to the side support arm of the fork-mounted frame 3. The boss 4 has a slot 401 on the side facing the limiting pin 5, which engages with the front end of the limiting pin 5. The limiting pin 5 is slidably connected to a pin seat 501, which is fixed to the side support arm of the fork-mounted frame 3. The axle 6 is fixed to the lower part of the balance beam 1 and is arranged perpendicular to the balance beam 1. Rollers 601 are provided at both ends of the axle 6. Electrolyte tank 7 is placed in the middle area of ​​fork rack 3. Balance hangers 701 are fixed on both sides of electrolyte tank 7. Balance hangers 701 are cylindrical and abut against ear grooves 301.

[0025] In this embodiment, a spring 502 is sleeved on the limiting pin 5. The front end of the spring 502 abuts against the retaining ring 503, which is fixed to the limiting pin 5. The rear end of the spring 502 abuts against the pin seat 501. A pull rope 8 is provided at the rear of the limiting pin 5. One end of the pull rope 8 is fixed to the limiting pin 5, and the other end extends to the hand-held crossbar 2.

[0026] In this embodiment, a counterweight 9 is provided at the rear of the balance beam 1, and the counterweight 9 is connected to the balance beam 1 by a suspension rope 901. A plurality of spaced-apart stops 10 are provided at the rear of the balance beam 1, and the suspension rope 901 rests against the stops 10.

[0027] like Figure 4 As shown, the operation process of this utility model is as follows: After the operator scoops the liquid electrolyte into the electrolyte tank 7 to full, the operator operates the transport trolley so that the two ear slots 301 on the fork rack 3 are hooked with the balance hanging ears 701 on the two side walls of the electrolyte tank 7. The pull rope 8 is released, and the limiting pin 5 is inserted into the slot 401 of the boss 4 under the action of the spring 502. In this way, the blocking of the limiting pin 5 can prevent the balance hanging ears 701 from coming out of the ear slots 301. The force on the hand handle 2 on the transport trolley is adjusted by using the movable counterweight 9. The transport trolley is pushed to the target electrolytic cell where liquid electrolyte needs to be replenished. The bottom of the electrolyte tank 7 is lightly placed on the edge of the aluminum outlet. The electrolyte tank 11 is tilted by pushing lightly, so that the liquid electrolyte in the tank can be poured into the tank. The above process is repeated to complete the adjustment of the liquid high temperature electrolyte level.

[0028] Example 2

[0029] Based on the forklift structure 3 in Embodiment 1 above, the charcoal slag box 12 can be transported, such as... Figure 5 and 6 As shown, the slag box 12 has a top-opening structure with an outer edge at its top edge. The outer edge of the slag box 12 can rest against the forklift rack 3. To ensure the stability of the slag box 12, an auxiliary support block 11 is provided at the top of the forklift rack 3. The auxiliary support block 11, the boss 4, and the pin seat 501 are all at the same height.

[0030] It should be noted that the slag removal work of the electrolytic cell is one of the essential daily operations. The slag from the electrolytic cell is removed into the slag box 12, and the slag box is moved to the designated area for storage using a transport cart for unified recycling.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
